The specific embodiment:

Below in conjunction with accompanying drawing the utility model is further described.

The following stated only is a better embodiment of the present utility model, does not therefore limit protection domain of the present utility model.

See accompanying drawing 1,2,3, the utility model comprises cross bar 10, is arranged with motion bar 20 in the cross bar 10 vertically, forms guard bar 30 respectively on cross bar 10, the motion bar 20, two guard bars 30 are used for fastening respectively the both sides of steering wheel, form at least two breach on the motion bar 20; Coded lock 40 is installed on the cross bar 10, coded lock 40 drives locking bar 50, one end of locking bar 50 penetrates cross bar 10 back and cooperates screens with breach on the motion bar 20, and the screens of two breach by locking bar 50 and motion bar 20 can realize folding and launching of motion bar 20; The input password, make coded lock 40 drive locking bar 50 and outwards move the disengaging breach, releasing is to the restriction of motion bar 20, then motion bar 20 is pulled outwardly, and make guard bar 30 fasten steering wheel, again locking bar 50 is inwardly pushed away and is stuck in another breach of motion bar 20, can not move with coded lock 40 restriction locking bars 50 at last, realize locking steering wheel; When unblanking, only need reverse operating to get final product.

Described coded lock 40 comprises fixed lock core 42, transfers code wheel 44, cipher wheel 46, locking bar 50, fixed block 48, wherein:

Fixed lock core 42 is cylindrical, and its inner is fixed on the cross bar 10, elastic component 424 is installed on the outer face, forms the groove 422 that runs through fixed lock core 42 along the axis direction of fixed lock core 42, and the body of rod of locking bar 50 places in the groove 422, and locking bar 50 can move forward and backward along groove 422;

Transfer code wheel 44, cipher wheel 46 all to be sheathed on fixed lock core 42, the locking bar 50, transfer code wheel 44, cipher wheel 46 to rotate around fixed lock core 42; Transfer code wheel 44 to be sheathed in the cipher wheel 46, transfer code wheel 44 radially to have breach 442, a side of cipher wheel 46 is radially extended inwards and is contacted with transferring code wheel 44, has hoodle, pit linkage between the contact surface of accent code wheel 44 and cipher wheel 46;

Locking bar 50 outermost end have the catch 52 that cooperates with elastic component 424, and when the input password, when removing the restriction to locking bar 50, elastic component 424 can outwards eject catch 52, and locking bar 50 is outwards moved, and releasing is to the restriction of motion bar 20; Form on locking bar 50 bodies of rod and the breach 54 of transferring code wheel 44 to cooperate, under the locking state, transfer code wheel 44 to be stuck in breach 54 places of locking bar 50, locking bar 50 can not move, under the unlocking condition, transfer the breach 54 of the breach 442 aligning locking bars 50 of code wheel 44, remove restriction locking bar 50, locking bar 50 can move forward and backward, and locking bar 50 body of rod sides form mounting hole 56;

Fixed block 48 is fixed in the outermost end of fixed lock core 42, and fixed block 48 is used for restriction and transfers code wheel 44, cipher wheel 46, and they can not broken away from fixed lock core 42;

Fixedly be equipped with the gag lever post (not shown) in the groove 422 of fixed lock core 42, gag lever post is placed in the mounting hole 56 of locking bar 50, and mounting hole 56 can limit the moving range of locking bar 50.

Described hoodle, pit linkage adopt following structure: transfer the side of code wheel 44 to offer a plurality of pits 444, cipher wheel 46 and accent code wheel 44 contacts side surfaces, on this contact surface of cipher wheel 46 elasticity hoodle 464 is installed, transfer code wheel 44 and cipher wheel 46 to be linked in a time-out, by the interaction of elasticity hoodle 464 with pit 444, rotational password was taken turns 46 o'clock, transferred code wheel 44 to rotate together, and cipher wheel 46 is when exchanging code wheel 44 mutually and rotating, and the elasticity hoodle can increase feel with also cooperating of pit.

Described cipher wheel 46 appearances are carved with anti-skidding line 462, strengthen feel.

Described fixed lock core 42 surfaces are stairstepping, guarantee the crudy of theftproof lock.

Be arranged with contraposition wheel 60 on the described fixed lock core 42, contraposition is taken turns 60 surfaces and is carved with reference line 62, under the situation that a plurality of cipher wheel 46 are arranged, can increase the quantity of contraposition wheel 60, fixed lock core 42 surface formings have the backstay (not shown), backstay takes shape in the bottom of fixed lock core 42, the quantity of backstay is consistent with the quantity of contraposition wheel 60, contraposition wheel 60 radially offers two

breach

64,66, these two

breach

64,66 cooperate with locking bar 50 and backstay respectively, backstay cooperates with the breach 66 of contraposition wheel 60, can limit contraposition wheel 60 and can not rotate, and guarantees reference line 62 invariant positions.

The side of described contraposition wheel 60 is equipped with elasticity hoodle (not shown), transfers two sides of code wheel 44 all to offer a plurality of pits 444, and the elasticity hoodle of contraposition wheel 60 also can cooperatively interact with the pit 444 of transferring code wheel 44, increases feel.

For coded lock 40, under the locking state, rotational password wheel 46 under hoodle, the effect of pit linkage, transfers code wheel 44 along with cipher wheel 46 is rotated together, transfers breach 54 rotations of code wheel 44 along locking bar 50, and locking bar 50 is in the lock state; When all cipher wheel 46 all are transferred to correct password position place, at this moment, transfer breach 442 on the code wheel 44 to be in breach 54 tops of locking bar 50, locking bar 50 no longer is restricted, under the elastic force effect of the elastic component 424 of fixed lock core 42, the catch 52 of locking bar 50 is outwards ejected, locking bar 50 outwards moves, and is subjected to the gag lever post effect in the groove 422, and locking bar 50 stops after outwards moving a bit of distance, the mobile restriction that can guarantee to remove to motion bar 20 of locking bar 50 realizes unlocking condition; Under this unlocking condition, locking bar 50 blocks the breach 442 of transferring code wheel 44 just, makes to transfer code wheel 44 not rotate, and at this moment, rotational password wheel 46 promptly can realize being provided with new password.

Outer wrap one deck plastic cement of the utility model theftproof lock is avoided producing wearing and tearing between metal theftproof lock and the steering wheel, strengthens result of use.

Because the utility model does not need key by the control of password realization to theftproof lock, and is very easy to use, and security performance is preferable.
